Description

Technical Field

[0001] The utility model relates to the technical field of oil field production, in particular to a special tool for taking out sealing fillers of a Christmas tree. Background Art

[0002] An oil well is a hole drilled by drilling methods. Generally, after the oil well reaches the oil layer, the oil layer casing is lowered, and oil well cement is injected into the annular space between the casing and the well wall to maintain the well wall and seal the oil, gas and water layers. Then, according to the requirements of oil field development, the oil layer is opened with a perforating gun to form a channel, and the oil pipe is lowered. The oil is raised from the bottom of the oil well to the wellhead by using appropriate flow induction methods. In the current oil well production process, replacing the sealing packing of the oil tree of the pumping unit is one of the basic tasks that oil workers must do almost every day. The sealing packing refers to the root packing of the oil tree, which is usually woven from a relatively soft thread. It is usually cut into The square, rectangular or circular strips are filled in the sealing cavity. The working principle of the packing is that the surface of the pump shaft of the oilfield water injection pump is very uneven under microscopic conditions and can only partially fit with the packing. Therefore, there is a tiny gap between the packing and the shaft, just like a maze. The medium is intercepted many times in the maze, thereby achieving a sealing effect. The packing packing's compression force on the shaft is generated by tightening the gland bolts. Since the packing is an elastic-plastic body, when it is axially compressed, friction is generated, causing the compression force to gradually decrease along the axial direction. At the same time, the radial compression force generated makes the packing close to the shaft surface to prevent the medium from leaking out.

[0003] The existing Christmas tree packing box is used to remove the sealing packing using a flat screwdriver. Since the packing is compressed one by one, it is difficult to remove it. If the operation is not done properly, it is easy to cause injury to people. According to the search report of the new search agency, the announcement number CN219311196U discloses a special tool for removing the Christmas tree sealing packing, which includes a special tool body, a sleeve and two clamping components. The clamping component is arranged inside the sleeve, and the special tool body is arranged inside the sleeve; the clamping component includes a handle, a through hole, a clamping block and an elongated groove. The middle part of the handle is provided with a through hole, the outer side of the sleeve is provided with an elongated groove, and the two sides of the elongated groove are slidably connected with the clamping blocks, which cooperate with the corresponding through holes. After the special tool body is used to hook out the old sealing packing, the sleeve is inserted from the bottom of the special tool body, and the special tool body and the sleeve are connected by screws. Then the handle is rotated downward, and the handle is folded inside the elongated groove through the cooperation of the through hole and the elongated groove, which is convenient for carrying after use. The sleeve is wrapped to prevent workers from being injured, play a protective role, and is conducive to practical application.

[0004] The above-mentioned technology discloses a special tool for removing the sealing packing of a Christmas tree. A curved groove is provided at the bottom of one side of the special tool body to form a hook. The curved groove is used to hook and remove the sealing packing. This method is similar to the traditional method of prying out with a flat-blade screwdriver. However, it has the following shortcomings during use:

[0005] 1. Since the sealing packing (root packing) is tightly squeezed against the inner wall of the Christmas tree packing box, there is almost no gap, or the gap is very small, making it difficult to insert the end of a screwdriver or the hook to pry or pull it, which is very restrictive. It cannot automatically form an integral part with the sealing packing and can be removed conveniently and labor-savingly, which is time-consuming and labor-intensive, and the removal efficiency, convenience and stability are not ideal. In view of this, the present application proposes a special tool for removing the Christmas tree sealing packing to solve the above-mentioned problems. Utility Model Content

[0026] A threaded vertical guide lifting assembly for lifting and adjusting is installed in the rectangular box 1. A storage cylinder 7 with an opening at the bottom is fixedly connected to the right side of the threaded vertical guide lifting assembly. A telescopic drilling and pulling and removing assembly for drilling and connecting the sealing filler 101 is installed in the storage cylinder 7; the threaded vertical guide lifting assembly is used to drive the storage cylinder 7 to move up and down for adjustment work, and the telescopic drilling and pulling and removing assembly is used to rotate downward and move out from the storage cylinder 7 to drill into the sealing filler 101 to form an integrated whole, and is used to directly pull and remove the sealing filler 101 upward when the storage cylinder 7 moves upward after drilling to form an integrated whole. The provided storage cylinder 7 is used to store and protect the telescopic drilling and pulling and removing assembly after use to prevent damage.

[0027] Specifically, the threaded vertical guide lifting assembly includes two T-shaped guide rails 4 fixedly connected to the left inner wall of the rectangular box 1, and the same lifting seat 6 is slidably installed on the two T-shaped guide rails 4, wherein the left side of the lifting seat 6 is provided with two T-shaped slide grooves with openings at the top and bottom, and the T-shaped slide grooves are slidably connected to the corresponding T-shaped guide rails 4, which play the role of guiding the vertical sliding of the lifting seat 6, and the right side of the lifting seat 6 is fixedly connected to the left side of the storage tube 7. A first screw rod 3 is rotatably installed on the bottom inner wall of the rectangular box 1, wherein a bearing is fixedly connected to the bottom inner wall of the rectangular box 1, and the inner ring of the bearing is fixedly fitted to the outer side of the first screw rod 3, which plays the role of rotatable installation of the first screw rod 3. As a result, the lifting seat 6 is threadedly sleeved on the first screw 3, wherein the top of the lifting seat 6 is provided with a threaded hole threadedly connected to the first screw 3. The threaded connection between the first screw 3 and the threaded hole is utilized to facilitate the effect of driving the lifting seat 6 to move up and down when the first screw 3 rotates. The top of the rectangular box 1 is embedded with a first motor 5 fixedly connected with the output shaft and the top of the first screw 3; the T-shaped guide rail 4, the lifting seat 6, the first screw 3 and the first motor 5 are coordinated, and the first motor 5 is used to drive the first screw 3 to rotate. The rotation of the first screw 3 drives the lifting seat 6 to move up and down, and the lifting seat 6 drives the storage tube 7 to move up and down for adjustment or to provide upward pulling force.

[0028] Furthermore, the telescopic drilling and pulling removal assembly includes a nut 11 fixedly sleeved in the storage cylinder 7, a second screw 9 is threadedly sleeved in the nut 11, the tops of both sides of the second screw 9 are fixedly connected with anti-slip blocks located above the nut 11, the bottom end of the second screw 9 is fixedly connected with an auger blade 13, a second motor 8 is fixedly installed on the top of the storage cylinder 7, the output shaft of the second motor 8 extends into the storage cylinder 7 and is fixedly connected with a square rotating rod 10, the second screw 9 is slidably sleeved on the square rotating rod 10, wherein the second screw 9 The top is provided with a square slide groove 12 which is slidably fitted with the outer side of the square rotating rod 10. The sliding fitting relationship between the square rotating rod 10 and the square slide groove 12 is used to facilitate the vertical sliding of the second screw rod 9 on the square rotating rod 10 through the square slide groove 12. The square member has the characteristic of fitting the edges and corners together, which facilitates the second screw rod 9 to rotate as a whole by fitting the edges and corners of the square slide groove 12 when the square rotating rod 10 rotates, providing the second screw rod 9 with the conditions for integral rotation and vertical displacement. The nut 11, the second screw rod 9, the auger blade 13, The second motor 8 cooperates with the square rotating rod 10, and the second motor 8 drives the square rotating rod 10 to rotate in the forward direction. When the square rotating rod 10 rotates, the second screw 9 is driven to rotate as a whole through the corners of its square piece. The second screw 9 rotates in the nut 11 and moves downward.

[0030] The method of using this embodiment is as follows: when using, when taking out the sealing filler 101, the L-shaped rubber pad 14 at the bottom right side of the rectangular box 1 is clamped on the edge corner of the top side of the oil tree packing box 100 to provide a support force point, and the first motor 5 is started in the positive direction to drive the first screw 3 to rotate. The rotation of the first screw 3 drives the lifting seat 6 to slide downward on the T-shaped guide rail 4. When the lifting seat 6 drives the storage cylinder 7 to move down and contact the top of the sealing filler 101, the first motor 5 is turned off. At this time, the personnel starts the second motor 8 in the positive direction. The second motor 8 drives the square rotating rod 10 to rotate. When the square rotating rod 10 rotates, the edges and corners of the square part of the square rod 10 collapse and drive the second screw 9 to rotate as a whole. The second screw 9 rotates in the nut 11 and moves downward. When the second screw 9 rotates and moves downward, it drives the auger The feed blade 13 rotates and moves downward to perform the removal work. The rotating downward auger feed blade 13 gradually drills downward into the sealing filler 101 and forms an integral part with it by drilling. At this time, the first motor 5 is started in the reverse direction. Similarly, the movement direction of the first motor 5 is completely opposite to the above-mentioned forward start. At this time, the storage cylinder 7 changes to move upward, and drives the auger feed blade 13 to move upward through the nut 11 and the second screw 9 in turn. The auger feed blade 13 pulls the sealing filler 101 formed with it upward and removes it, achieving the effect of automatically drilling into the sealing filler 101 to form an integral part and conveniently pulling it out. The method of forming an integral part by drilling and automatically pulling is not affected by gap factors, and does not require manual prying or laborious pulling, which saves time and effort and improves the removal efficiency, convenience and stability.

[0031] In addition, to further ensure the removal stability, personnel can also use two devices to simultaneously perform drilling and pulling removal work on both sides of the sealing filler 101. It is also possible to perform drilling and pulling removal work on the other side after pulling out one side, which can be flexibly used according to the on-site conditions.

[0032] After taking it out, start the second motor 8 in the reverse direction. Similarly, the movement direction is completely opposite to the above-mentioned forward start of the second motor 8. At this time, the auger feed blade 13 changes to a rotating and rising state. At this time, the rotating and rising auger feed blade 13 gradually retracts into the storage tube 7 and is stored, shielded and protected by it, achieving the effect of storing and hiding the auger feed blade 13 after use, reducing the risk of accidentally scratching or accidentally bumping people when carrying, ensuring safety when carrying, and facilitating people to carry and work safely.

[0033] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents.
